ABSTRACT:
An interlock arrangement for a pair of aligned switches, for preventing both switches from being on at the same time, includes a feature that prevents the switches from being inadvertently disengaged from mounting structure associated with an electrical panel to which the switches are mounted. The interlock arrangement includes an interlock base member that extends through aligned openings defined by the switch operating members. A pair of inner engagement members interact with the switch operating members so as to ensure that the switch operating members cannot both be in the ON position. An outer engagement member is secured to the interlock base member outwardly of each switch operating member. The interlock base member overlies and engages edges defined by the switches and the outer engagement members engage the switch operating members, to prevent inadvertent removal of the switches. The interlock arrangement further includes a retainer for preventing inadvertent disengagement of the inner engagement members from the interlock base member.
