PUSH BUTTONS AND OPERATOR
INTERFACE
[1] Trigger action mushroom heads are tamper proof in that a change of contact state is not possible by teasing or floating the operator. For emergency stop applications, always use a trigger
action push button (per EN/IEC 13850).
[2] For contact configurations, see Sequence of Contacts on Selector Switch Bodies, page 19-30.
