No. The 56PB only comes with a Normally Open Contact, as it is a singular operating button and non-latching.
If they are looking for a stop/start operating push button, they would be better suited to use a 56/2PB as this has both the "start" (N/O contactor) and "stop" (N/C contactor)
Some of the features of this product include.
- Green Start Push Button
- Red Stop Button
- Clearly maked front cover
- IP66 Rated
