42MT Solenoid Switch
Delco-Remy

The 42MT solenoid switch represents a rugged actuation device designed to manage energization of associated solenoid circuits in demanding truck environments. With 12-volt operation and a solenoid-controlled switching mechanism, this component enables reliable remote and direct control of critical systems such as starters, pumps, or hydraulic valves under severe duty cycles. Its weather-resistant construction, combined with solid electrical connections, reduces risk of intermittent switching caused by dust, water, or road salt exposure. In practical terms, fleet operators benefit from consistent start-up performance, improved control fidelity, and reduced diagnostic time when troubleshooting electrical harnesses. The VMRS code 032-002-012 anchors it in the solenoid switch family, and its category 77127 confirms its role in durable control devices that enable efficient, safe operation of heavy-duty powertrains across varied service conditions.
