A control lever is provided for actuating a deadman's switch or any other switch actuatable by a lever. The control lever is resilient and includes a base portion fixed to the support on which the switch is mounted and an actuator portion which is formed integral with the base portion and which extends over the switch. The actuator portion is deflectable into contact with the switch without the interaction of any pivot element, hinge, or any other connection of the control lever to the support. The lever can be easily actuated with any portion of the operator's hand and preferably is sufficiently resilient to prevent the function of the switch from being defeated by the insertion of a facing object between the lever and the switch and to prevent or at least inhibit damage to the switch due to overpressure on the lever. The lever is preferably pliable and thus can be bent or twisted in virtually any direction without damaging the lever.
