AMS Reversing SwitchThe AMS Reversing Switch is an AC drum switch that is used as the reversing control for the electric motors on our gear products. The switch is available in both a spring (momentary) or maintain (latching) version. The spring type is a good safety as it only allows power through to the motor while your hand is physically moving the handle to the UP or DOWN position, otherwise it springs back to the OFF position. Customizable with different control
