Albright 24 Volts DC motor-reversing solenoid contactor, intermittent.
- The DC88-267L series of contactors (with large tips) have been designed for direct current loads, particularly motors 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 compatible with modern electronic control systems.

About The DC88-267L 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 6.3mm spades, 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). |
