Morris 70290 Momentary-Contact Toggle Switch, DPDT, On-Off-(On), 20A

Product Overview

The Morris 70290 is a heavy‑duty, momentary‑contact double‑pole double‑throw (DPDT) toggle switch with an On‑Off‑(On) action — the parenthesized On position is spring‑returned (momentary).

It uses screw terminals and a threaded bushing for panel mounting. Electrical ratings: 20A at 125VAC, 10A at 250VAC and 277VAC, and a motor load rating of 1½ HP at 125–250VAC.

Key Features

• DPDT (double‑pole, double‑throw) On‑Off‑(On) spring‑return momentary action
• Rated 20A @ 125VAC; 10A @ 250VAC and 10A @ 277VAC
• 1‑1/2 HP motor load rating at 125–250VAC
• Screw terminals for wiring
• Threaded bushing for panel mounting
• UL listed

Function and switching action

The Morris 70290 is a DPDT toggle switch with an On‑Off‑(On) action. The Off position is stable; the second On position is momentary — the toggle springs back from that momentary position when released. This provides a stable center‑off and a spring‑return auxiliary contact for momentary control.

• DPDT provides two independent poles, each with two throw positions
• On‑Off‑(On) where the second On is spring‑returned (momentary)

Electrical ratings and motor load

Use the 70290 within its published current and voltage ratings to match load requirements.

• 20A at 125VAC
• 10A at 250VAC
• 10A at 277VAC
• Motor load: 1‑1/2 HP at 125–250VAC

Mounting and wiring

The switch mounts through a panel using the threaded bushing and secures with a nut. Terminate wiring on the screw terminals. The toggle returns automatically from the momentary On position due to an internal spring.

• Panel mount via threaded bushing
• Screw terminals for field wiring

Typical applications

The 70290 is intended for momentary dual‑pole control such as motor jogging, start/stop stations, and spring‑return signaling where a momentary auxiliary position is required and the load falls within the electrical ratings.

• Jogging motors
• Start/stop control stations
• Momentary signaling circuits up to rated currents

Before You Order

Confirm the model number and quantity required before ordering. Verify that the electrical ratings and DPDT On‑Off‑(On) momentary action match your application requirements.

• Confirm panel hole size and bushing thread before installation
• Verify wiring and load ratings (20A@125VAC; 10A@250/277VAC) for your circuit
