Benefits
The SW200A-14 ensures high reliability and efficiency in applications where frequent switching under load is required. Its hard-wearing silver-alloy tips and double-break design make it a durable and safe choice, providing peace of mind in your DC power control systems.
Continuous contactors by design are predominantly used for drive functions on vehicles, they make and break slower than intermittent solenoids and are recommended for prolonged contact periods.
The SW200 has been designed for direct current loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW200 is suitable for switching Resistive, Capacitive and Inductive loads.
The SW200 features single pole single throw, double breaking main contacts with silver alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW200 has M10 stud main terminals and 6.3mm spade coil connections. It can be mounted via M5 tapped holes or steel mounting brackets - supplied as separate items). Mounting can be horizontal or vertical, when vertical the M10 contact studs should point upwards.
About the Albright SD200 Emergency Stop Switch The SD200 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 most small and medium-size electric vehicles. The SD200 has been designed to provide a rapid means of disconnecting 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 take place. However, if the knob is in the “On” position, the option of energizing the coil and thus closing the main contacts become available. The coil energization 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 Akun Hätä-Irtikytkentä Kytkin, manually depressing the operating knob will override the energized coil such that the main contact and the auxiliary contact - where fitted) will open until such time as the knob is again moved to the “on” position. Whilst the switches are primarily intended for use with battery-powered vehicles, they are also suitable for use with static power systems. All types are capable of safely rupturing full load battery currents in the event of an emergency. Uninterrupted current - no or infrequent load switching requirements - maintains a lower contact resistance).
