A wide range of Interlock Isolation switches is available from PSPC, providing the ideal control for use in majority of electrical machines systems. Rotary switch interlock can be supplied suitable for panel mounting or with enclosure, in current range from 20 to 150A, and any switching configuration may be supplied at short notice.
They are also available in multiple key versions to suit specific application.
The most commonly used 16A, 440VAC, 2NO 2NC configuration is available ex-stock or at short delivery.
Key Trapped in clockwise condition direction, rotary switch contacts NO become NC , NC become NO and Key released condition rotary switch contacts changed to the normal position NO and NC.

Example : ILE-P-N-2NO/2NC-16A-CW-0 : Rotary switch interlock, pin type, Brass, Nickel Plated, clockwise,2 NO+2NC contacted 16A rated, without flip cap.
These Bolt Interlocks incorporate an integral positive drive operation of a limit switch rated at 240VAC 10A. Other rating available on request. They are intended to provide remote status indication or to operate associated equipments such as exhaust fans or illuminations.
Key Trapped in clockwise condition, bolt retracted from its position, and now limit switch contacts changed its original position. NO become NC, NC become NO and Key released condition bolt extended to initial length 20mm (L+20mm), and limit switch changed to the normal position.

The range of solenoid released interlocked switches, provides for single and multiple key release applications. The key is released when energized by operating the control push button or key. The control push button (key) is operated to initiate the entry cycle. The machine then energizes the solenoid release when it is safe to enter and on removal of the access or secondary key(s) the machine power circuit is isolated. This unit is frequently used for the protection of robot cells, electrical enclosures, etc. the ILRO is housed in polycarbonate or sheet steel enclosure and is provided with mounting holes on the rear side of the enclosure.
Normally key trapped into the Solenoid interlock, when solenoid voltage signal received at solenoid, now Indication lamp glows, press the push button, and release the key, with this key open the door and other equipment.

The ILT interlock is designed for use in such applications in which a delay is required before access can be gained, or secondary operations undertaken. Integral isolation switches and an electronic time delay module are incorporated and the timer can be internally adjusted on installation within a specified range. Key in/ key out and multiple key versions are available to suit any required configuration.
In certain applications the hazard is not removed immediately after power isolation.
Example : Large fly wheels continue to rotate after power isolation due to inertia. Capacitors discharge gradually after power isolation.
Normally key trapped into the Solenoid interlock, when solenoid voltage signal received at solenoid, now timer starts and after setting time of timer, Indication lamp glows, press the push button, and release the key, with this key open the door and other equipment.
