Abstract
A push-to-turn knob design for a rotary switch to prevent accidental actuation of the switch by requiring a two-step operation sequence. This operating function is obtained without modifying the design of the rotary switch. Hence, a standard rotary switch can be easily converted to a push-to-turn operating sequence.
