Albright 12 Volts DC motor-reversing solenoid intermittent contactor with dust shields.
- The DC88-440 series of contactors has been designed for direct current loads, particularly motors as used on small electric vehicles such as light industrial trucks, powered invalid cars, etc.
- They have double-breaking main contacts with Silver-alloy contact tips, which are weld-resistant, hardwearing and have excellent conductivity.
- They are economical in price and compare favourably with sealed automotive-style solenoid switches, which cannot be serviced or inspected for contact wear.
- The DC88 is a monoblock construction, resulting in a neat, compact design which is compatible with modern electronic control systems.
- Flying coil leads fitted to this version for energising, minimum 160mm, maximum 165mm long.
- Dust shields fitted both sides of the top cover.

About The DC88-420 Motor Reversing Solenoid
Intermittent contactors, by design, are predominantly used for hydraulic functions on vehicles; they make and break quicker than continuous solenoids and are not recommended for prolonged contact periods.
The main contact circuit, designed for motor reversing, has a built-in failsafe, so that if both coils are energised simultaneously, the contact arrangement is an open circuit. Coil connections are by means of flying leads, and mounting is via M4 screws on a panel fixture or using an additional bracket (e.g. part number: 2070-41) and can be horizontal or vertical. When vertical, the M8 contact studs should point upwards.
Interrupted Current: The opening and closing on load with frequent switching (resulting in increased contact resistance). |
Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance). |
