Choosing an Electrical Switch

About Door Closers

When replacing an existing closer, remove the cover and match the model number and/or mounting hole pattern to a closer in our offering. Or, use one of our closers and a universal mounting plate that matches most hole patterns.

If you are installing a new closer, choose one that works for your door width. Due to added resistance from wind, closers typically accommodate smaller exterior doors than interior doors.

Mounting Positions

There are three typical mounting positions for door closers; many of our closers are versatile and can be mounted in any of these positions. To determine opening direction, stand on the side of the door where the closer will be mounted. If the door opens towards you it opens in; opens away from you it opens out.

Door Mount, Opens In—Also known as regular arm mount, this position allows the door to open in toward the closer.

Door Mount, Opens Out—Also known as parallel arm mount, the arm lays parallel with the door in the closed position.

Frame Mount, Opens Out—Also known as top frame mount, this position is often used for exterior doors.

Automatic Door Switches

Hardwire these switches to automatic door openers, electromagnetic locks, and electric strikes to open doors with the touch of a button or wave of a hand. Mount them to electrical boxes or surface-mount boxes (sold separately). Instant-open switches provide immediate access. Time-delay switches allow time to reach the door before it opens.

Style 1-7 switches operate with the touch of a button. Style 7 switches are 36 in. tall, so they’re easy to push with a foot, cane, crutch, or other device.

Automatic Overhead Door Openers

Also known as jackshafts, these openers operate 24-ga. or thinner overhead doors. The opener will stop and reverse the door's downward motion if it encounters an obstruction when closing or the light beam between the opener's light beam sensing switches is interrupted. During a power failure, use the manual chain hoist to move the door. All of these openers meet UL 325 safety standards for door operators and systems.

When facing the side of the door with the opener, a right-side mount opener is located on the right side of the door, left-side mount is on the left. An optional remote transmitter is sold separately.

Outlet-Box-Mount Key Switches

Reset fire panels, or open electromagnetic locks, electric strikes, and automatic door openers. These switches require a key to turn circuits on or off, limiting access and preventing accidental activation. The lock is not included; use a 1 1/4" long mortise lock with a standard cam.

Switches with a delayed start timer allow personnel to reach a door before it opens.
