MODEL 328: HEAVY-DUTY WATERPROOF MOMENTARY PUSH BUTTON SWITCH

WEATHERPROOF OFF-ROAD COMMAND SWITCHING

Bring uncompromising weather resistance and immediate command to your vehicle accessories with the premium Kleinn Model 328 Heavy Duty Waterproof Push Button Switch. Explicitly engineered to survive extreme operating conditions, this rugged black momentary button allows you to manually trigger the full blast of your train horns or onboard air systems directly from the driver's seat. Encased in a structural protective shield, it delivers an instantaneous, crisp electrical connection cycle with zero execution lag on every single press.

HEAVY-DUTY ELEMENT ISOLATION

The Model 328 features a specialized protective heavy-duty rubber cover designed to seal out trail mud, fine dust fields, and water spray. This non-locking momentary contact button remains closed only while actively depressed, springing open automatically the moment pressure is released to safeguard downstream solenoids from continuous electrical load. Outfitted with heavy-gauge screw terminals to ensure simple, rock-solid wire connections, this weatherproof control switch mounts cleanly into rugged off-road dashboards, open-cab center consoles, or exposed service panels.

Why Choose the Model 328 Switch?

  • Waterproof Rubber Shroud: Integrated premium heavy-duty rubber boot seals out moisture and trail debris, making it ideal for open Jeeps, UTVs, or exposed chassis locations.
  • Crisp Momentary Response: Non-latching spring action returns the contact button instantly to the off position, providing complete manual timing over each horn blast cycle.
  • Easy Screw-Type Terminals: Outfitted with integrated screw terminals to ensure simple, rock-solid wire connections that resist heavy off-road chassis vibrations.
  • Universal 12V Applications: Serves as an ideal activation source for electronic solenoid air valves, backup sirens, starter relays, or off-road auxiliary relays.

THE VERDICT: The definitive waterproof control button for high-output setups. The Model 328 combines absolute element isolation with rugged vehicle integration to ensure your train horns trigger instantly on the highway or out on the trail.

What's Included in the Box

  • Cockpit Switch: One (1) Model 328 heavy-duty waterproof black push button switch.
  • Weatherproof Barrier: One (1) integrated protective heavy-duty rubber cover shroud.
  • Terminal Screws: Pre-installed screw-type terminal hardware for direct electrical wire securement.

🔴 PRO TIP: Keep your electrical circuits balanced and protected. When plumbing this manual trigger to a heavy-flow compressor loop, always route your high-current power path through an isolated 40-amp automotive relay like our fully sealed Kleinn Part #340 to insulate your dashboard switches from high-amperage spikes.
