Crouzet 83133 subminiature snap-action microswitch (double-break Form Za). NOT a 15A V-15-class switch. Order by full 83133-XXX code for actuator/terminal.
การใช้งานทั่วไป
French-made miniature microswitch found in European appliances, HVAC equipment, and vending machines. The European counterpart to the Honeywell V-15. Used as door interlocks on washing machines, safety switches on gas boilers, and limit sensors on pneumatic cylinders. Crouzet microswitches are specified by Airbus for aircraft cabin equipment.
Research Notes
1. Overview
The Crouzet 83133 is a subminiature snap-action basic switch, part of the 83132 / 83133 / 83134 double-break family from Crouzet Switch Technologies (a French/Innovista brand). It is a small changeover (SPDT, double-break Form Za) microswitch offered with a wide range of actuators (pin plunger, lever, roller lever, simulated roller) and rear/side/front terminal outputs. "83-133-0" as stored is a family/base reference; real orderable part numbers carry a 3-digit suffix (e.g. 83133169 pin plunger, 83133191 bistable), each specifying actuator + terminal.
2. User Sentiment
As an industrial component it has little consumer sentiment, but it is a long-standing, well-regarded European alternative to subminiature switches from Honeywell/ZF/Omron. Engineers value the double-break contact (better arc handling / higher isolation than single-break at this size) and the breadth of actuator options. Stocked by Mouser, Newark, Allied, and RS.
3. Real-World Applications
Position sensing and limit switching in industrial valve/actuator positioners, small appliances, HVAC, and equipment interlocks — anywhere a compact, reliable snap-action detector is needed. The double-break variant is specifically suited to detection/switching in positioning units.
4. Technical Specifications
- Type: Subminiature snap-action basic switch, double-break changeover (Form Za)
- Contacts: SPDT (double break) — NO + NC
- Rating: up to 5 A / 250 V AC (subminiature class — NOT a 15 A switch)
- Operating force: ~1.6 N max (actuator-dependent)
- Terminals: solder / quick-connect, rear-side-front output options
- Actuators: pin plunger, straight/roller lever, and others (per suffix)
- Approvals: UL, VDE, CE (per specific part)
5. Ordering & Compatibility
Order by the full 83133-XXX code for a specific actuator/terminal (e.g. 83133169). The 83132/83134 siblings share the body with different contact/terminal arrangements. NOTE: the 83133 subminiature is not equivalent to a Honeywell V-15 (that is a larger 15 A "full-size" basic switch); a closer Crouzet analogue to the V-15 would come from a larger Crouzet basic-switch series, not the 83133.
6. Known Issues
No notable reliability issues; a mature snap-action design. The main selection pitfall is rating confusion — the subminiature 83133 (~5 A) is easily mistaken for a full-size 15 A basic switch, which it is not.

คู่มือการติดตั้งอย่างรวดเร็ว
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

การแก้ไขปัญหา
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
