Choosing an Electrical Switch

Two-Hand Safety Switches

It takes two hands to activate these switches, minimizing the risk of accidental equipment start up. They have an emergency stop push-button to immediately cut power. They’re rated IP65 for protection from low-pressure washdowns.

Switches with finger-touch actuators turn circuits on and off with a light touch, even when wearing gloves. An infrared sensor detects the lightest finger contact, and an indicator lights up to confirm when they are activated. Because they don't require you to press down a button to operate, they meet ANSI B11.TR1 standards to reduce hand, wrist, and arm fatigue. You'll need a relay or controller to complete your system—upgrade to a controller if you plan to operate additional devices beyond your switch.

Safety controller expansion modules can be added to safety controllers to increase the number of inputs.

Telescoping stands can be added to switches with finger-touch actuators to mount them away from a wall. The stands telescope to adjust the height of the switch and tilt to adjust the angle of the switch.

Light Beam Finger-Touch Switches

An infrared light beam senses the lightest finger contact to switch a circuit on or off. The included guard prevents accidental activation. An indicator lights up to confirm that switches are actuated. They’re rated NEMA 4X, 13, and IP66 for protection from corrosion, washdowns, and oil/coolant spraying.

Switches with a 5-pole mini plug can quickly be changed out.

Fingerprint Switches

Switch

Cover

Use fingerprints to confirm the identity of personnel before granting access to secure areas or equipment. Switches light up green to indicate that they have accepted the fingerprint and are sending an output signal. The front faces of the switches meet NEMA 12 and IP65. The rear faces of the switches meet IP20.

Covers (sold separately) have an adhesive-back hinge, so you can stick them on to your switch. Keep the cover flipped down to protect the switch’s sensor from dust and debris.

Finger-Touch Switches

The light touch of a finger turns circuits on and off without pressing down a contact. Program these switches to fit your application—control their color, pattern, and sensitivity. Change the color to show different process statuses. For more visibility, change the intensity of the color or choose a light pattern. These switches can flash, rotate, and show other patterns, all at speeds you can control. To change how much force they need to actuate, alter the sensitivity. With a high sensitivity, they’ll actuate even if you’re wearing gloves. With a low sensitivity, they’re more resistant to accidental actuation.

To program your switch, download the free Banner Pro Editor Software. You’ll need a switch programming kit (sold separately) to connect your switch to the software.

Switches with a copolyester base are FDA compliant for incidental food contact once installed.

Switches with an audible alarm can be programmed to 12 different tones ranging from sirens to melodies.

Sealed Touch Pad Switches

Suitable for areas with space limitations, these switches have a low profile and a small footprint. They lay flat or mount to a wall. Typically used in start/stop and door opening applications, switches can also be placed underneath objects to alert when the object is removed. All have a sealed housing that resists water and alcohols (not suitable for continuous contact).

Optional mounting frames secure switches to a wall or bench top.

Easy-Clean Touch Light Switches

Flat and completely smooth, these switches are easy to wipe down. They’re rated NEMA 3R, so they seal out water that could damage the circuitry. They also won’t corrode from mild cleaning solutions. With just a light tap, you can switch lights on and off, even if you’re wearing gloves.

Switches with a stainless steel wall plate resist wear and tear better than switches with a plastic wall plate.
