71R1150 5-Terminal Rotary Blower Switch (Off–Low–Med–High), 25A 12V

Description

When a blower motor won’t stay on the right speed, the switch is often the first place to look. The Red Dot 71R1150 rotary blower switch is a 5-terminal switch designed for 3-speed blower control with a clear Off–Low–Med–High pattern.

Because this switch is rated 25 amps at 12VDC, it supports common heavy-duty HVAC blower loads. In addition, it uses 1/4″ male blade terminals, which makes it easy to connect with the correct harness. For best results, use the recommended 850-9522 wire harness.

Why This Switch Works Well

• Simple Off–Low–Med–High control for blower speed selection

• Heavy-duty rating for reliable performance

• Standard blade terminals for straightforward wiring

• Wide interchange coverage for fleet and OEM lookup
