- Connect safety
circuits to the NC contact (11-12 or 21-22). Contacts
are normally closed when the key is inserted into the
switch. Normally open contacts are for indicating circuits
- they are not to be used in the safety circuit.
- Mount the switch
and key using tamper-resistant fasteners (not supplied).
Use washers to prevent fasteners from pulling through
switch mounting holes.

has 2 key openings and can be rotated in 4 x 90 degree
steps allowing 8 different key entering positions. To
rotate the head insert the key, remove the 4 attachment
screws, rotate head into the proper position and reinsert
the attachment screws. See Figure 1.

- Do not use the switch
as a mechanical stop.
- Protect the key
entrance from dust and dirt.
- Verify proper safety
switch operation before placing the machine in service.
