Selection Notes
Key withdrawal limited to the left position means an operator can lock the switch there and remove the key, restricting the remaining positions to personnel holding a matching key 455 — the deciding factor over the handle-operated XA2AD selector switches where no key security is needed. With 1 NO, this variant drives a single switching point per key position. The deeper 88 mm body over the handle selectors’ 70 mm accounts for the key-lock mechanism behind the panel face.
