FLP / WP Control Station & Switch Gear | Patco Flameproof Products
In a normal industrial panel, a push button or rotary switch may look like a simple electrical component. But in a hazardous area, the same component becomes a safety-critical device.
A start-stop station near a chemical process line, a limit switch on a moving mechanism, a hooter in an emergency zone, or a manual call point near a storage area cannot be selected like ordinary switchgear. The enclosure, cable entry, contact rating, gas group suitability, IP protection, and flameproof construction all matter.
This is where FLP / WP Control Station & Switch Gear becomes important. These products are used where electrical switching, signaling, motor starting, machine control, and emergency indication are required in flameproof or weatherproof industrial environments.
For buyers, the main question is not only, “What is the price?” The better question is:
Will this control station be safe, compatible, and suitable for my actual hazardous-area application?
What is FLP / WP Control Station & Switch Gear?
FLP / WP control station and switch gear refers to flameproof and weatherproof electrical control products used for local machine operation, motor control, alarm activation, safety signaling, and switching in industrial areas.
In simple words, these are field-mounted control devices used by operators and maintenance teams near machines, process equipment, pumps, motors, conveyors, tanks, and hazardous-area installations.
The Patco FLP / WP Control Station & Switch Gear category includes products such as:
- FLP / WP Direct Entry Push Button Station
- FLP / WP Direct Entry Rotary Switch
- FLP / WP DOL Starter up to 10HP
- FLP / WP Hooter
- FLP / WP Limit Switch
- FLP / WP Limit Switch with Adjustable Long Lever
- FLP / WP Manual Call Point
- FLP / WP Rotary Switch
- FLP / WP Push Button Station
- FLP / WP Switch Socket with Plug
- FLP / WP Only Stop Push Button Station
- FLP / WP Only Start Push Button Station
- FLP / WP Push Button Station with Indicator
- FLP / WP Reverse-Forward Push Button Station
These products are designed for industrial locations where ordinary electrical devices may not be suitable due to hazardous atmosphere, dust, moisture, outdoor exposure, or safety requirements.
Why FLP / WP Control Stations Matter in Actual Plant Conditions
In actual plant conditions, control stations are touched, operated, exposed, and sometimes abused every day. Operators press start and stop buttons repeatedly. Maintenance teams isolate equipment. Safety teams need emergency signaling. Motors are started and stopped from field locations. Mechanical movement is detected through limit switches.
If the wrong control station is selected, problems can appear in multiple ways:
- Operator control becomes unreliable.
- The wrong contact configuration may not match the control circuit.
- Cable entry mismatch can delay installation.
- A non-flameproof product in a hazardous area can create a serious safety risk.
- Poor enclosure selection can cause moisture, dust, or corrosion-related failure.
- A wrongly selected DOL starter may not suit the motor rating.
- Limit switch actuation may fail if the lever type is unsuitable.
For hazardous areas, product selection is not only an electrical decision. It is a safety, compliance, maintenance, and uptime decision.
How FLP / WP Control Station & Switch Gear Works
The working principle depends on the product type, but the basic function remains the same: provide safe electrical control or signaling in a protected enclosure.
A push button station gives a momentary control signal to a motor starter, relay, PLC input, control panel, or safety circuit. A rotary switch allows selector-type operation such as ON/OFF, mode selection, or changeover. A DOL starter is used for direct motor starting. A limit switch provides position feedback from mechanical movement. A manual call point allows emergency alarm activation. A hooter provides audible indication during alarm or process warning conditions.
In hazardous-area applications, the enclosure and construction are as important as the electrical contact inside. The enclosure must suit the installation area, gas group requirement, cable entry arrangement, earthing requirement, and weatherproof protection level.

Key Selection Factors for FLP / WP Control Station & Switch Gear
1. Hazardous Area Classification
Do not select any flameproof product without confirming the hazardous zone, gas group, and approval requirement. The Patco range refers to flameproof protection standards such as IS / IEC 60079-1:2007 and gas groups including I, IIA, and IIB for listed products, but final suitability should always be checked against the actual plant classification.
2. Function Required
Decide whether you need start-stop control, emergency stop, rotary selection, motor starting, audible alarm, manual alarm activation, position feedback, plug-socket connection, or forward-reverse control.
3. Contact Configuration
Check whether your circuit needs NO, NC, or multiple contacts. For PLC input, starter control, relay logic, and safety circuits, contact configuration must be correct.
4. Voltage and Current Rating
For products like DOL starters, hooters, switch sockets, and rotary switches, rating is critical. Do not assume every control station suits every load.
5. Cable Entry and Gland Requirement
Cable entry such as M20 / 3/4” ET appears in the product details for several items. Before ordering, confirm cable size, gland type, entry quantity, and whether entries need to be customized.
6. IP Protection
IP protection matters in outdoor, dusty, washdown, chemical, or moisture-prone areas. The listed FLP / WP control station products include IP protection references such as IP-65 and IP-66 depending on item, so confirm the exact model requirement before final selection.
7. Operator Safety and Accessibility
Emergency stop, manual call point, hooter, and start-stop stations should be installed where operators can easily access them during normal operation and emergency conditions.
8. PLC / Panel / Starter Compatibility
If the device is part of a PLC, relay, starter, or SCADA-linked control system, confirm voltage, contact logic, terminal wiring, interlocking, and feedback requirement.
Common Applications
FLP / WP Control Station & Switch Gear is commonly used in:
- Chemical plants
- Solvent handling areas

- Oil and gas utilities
- Pharma process areas
- Food and beverage plants with washdown zones
- Pump houses
- Tank farms

Common Mistakes to Avoid
| Mistake | Why It Creates Problems |
|---|---|
| Selecting only by product name | The same product type can have different contacts, cable entries, ratings, and functions. |
| Ignoring gas group and hazardous-area suitability | A wrong enclosure selection can create safety and compliance risk. |
| Not checking NO / NC contact requirement | PLC, relay, and starter circuits may fail if contact logic is wrong. |
| Choosing a DOL starter without confirming motor HP and voltage | Motor protection and control may not match the actual motor. |
| Ignoring cable entry size | Installation gets delayed if cable gland and entry size do not match. |
| Using a standard limit switch where long lever is needed | Mechanical actuation may become unreliable. |
| Selecting hooter without checking supply voltage | 24V DC and 230V AC alarm circuits are not interchangeable. |
| Not confirming IP protection | Outdoor or wet-area installations may fail prematurely. |
Do This, Not That
| Do This | Not This |
|---|---|
| Confirm hazardous area, gas group, and IP requirement before purchase | Select only because the product is called flameproof |
| Check contact type, rating, and wiring logic | Assume every push button station matches every control circuit |
| Confirm motor HP before selecting DOL starter | Select DOL starter only by enclosure size |
| Check cable entry and gland requirement | Leave cable entry decision for installation day |
| Select adjustable lever type where mechanical alignment varies | Force a standard limit switch into a difficult location |
| Confirm supply voltage for hooter and indicator | Assume all alarm devices work on the same voltage |
| Match switch gear to PLC / relay / starter logic | Treat field control as a standalone item |
