Small and pressure-resistant
- Ideal for limited installation space
- Excellent for mounting in and on windings
Safe, reliable, durable
- Constant contact pressure over the entire temperature range
- For type 06, H6, RH double contact switch-off (NC contact) / switch-on (NO contact) due to higher current intensity
- About 70 tests during production ensure quality
- Worldwide approvals
- Very fast switching; therefore short duration of the arc effect on the contacts
Temperature sensitive
- Reproducible switching temperature due to mechanically and electrically unloaded bimetallic disk, factory-set nominal switching temperature(NST)
Fast response
- Good heat transfer to the rear derailleur due to very low switch mass
- With type P1 and W1 short switch-off times due to a defined series resistorRS
- Flexible use
- Wide supply voltage range with the exception of type R6,
- Extensive range of wires/strands
- For types P1 and W1, the heat output required for self-retaining is automatically regulated by a built-in PTC resistor RH (no overshoot)
Bimetal switch
When the factory-set nominalswitching temperature(NST) is reached, a bimetallic disk suddenly jumps from its stable starting position to a stable end position and actuates the rear derailleur.
Opener:
Types 01, Z1, P1, W1, 06, R6, H6, RH Contacts are disconnected and interrupt the circuit => direct switch-off
Closers:
Types 02, 08, 09 Contacts are closed and activate a circuit => e.g. activation of signaling devices.
Resetting:
Types 01,02, Z1, 06, 08, H6 If the temperaturefalls below the factory-set reset temperature(RST), the rear derailleur jumps back to its stable starting position.
Self-holding:
Types P1, W1 There is an integrated PTC heating resistor RH in parallel with the switching mechanism. After the contacts have opened, its heating power keeps the switching mechanism above the reset temperature until the supply voltage is interrupted. This function is used when automatic switching back after overheating and subsequent cooling is undesirable or not permitted. Check and/or service necessary!
