About The Albright SD150 Emergency Stop Switch

 Typically used on 24-volt DC systems as an emergency stop or kill switch.

 The SD150 has been designed to rapidly disconnect batteries or other power supplies in the event of serious electrical faults.

 The operation of the switch is such that with the operating knob depressed, i.e. in the "off" position, no electrical functions can occur. However, if the knob is in the "On" position, the option of energising the coil and thus closing the main contacts becomes available. The coil energisation can be carried out either through the vehicle key switch or as a result of a signal from the vehicle's electronic controller. When used as an emergency battery disconnect switch, manually depressing the operating knob will override the energised coil such that the main contact and the auxiliary contact (where fitted) will open until the knob is again moved to the "on" position.

 The SD150 combines the dual function of a manual disconnect and coil-operated line contactor. The benefits of this design include compact size and reduced installation costs combined with an electrical capacity sufficient for small and medium-sized electric vehicles.

 Whilst the switches are primarily intended for battery-powered vehicles, they are also suitable for static power systems. All types are capable of safely rupturing full-load battery currents in the event of an emergency.
