  • Publication number: 20190139725
    Abstract: A switching mechanism includes an actuator rotatable between an off position and an on position; and a timing disc assembly that includes an actuator disc, a bias disc, and a switch disc arranged in a stack. The actuator disc is rotatably connected to the actuator. The bias disc is connected to at least one biasing mechanism. The switch disc is connected to a switch. The actuator disc is configured to engage the bias disc such that the actuator disc is configured to rotate the bias disc to an overcenter position of the at least one biasing mechanism. The overcenter position of the at least one biasing mechanism is configured to rotate the bias disc such that engagement between the bias disc and the switch disc is configured to rotate the switch disc between a closed position and an open position of the switch.
