Illuminated and non-illuminated momentary pushbuttons give you complete control. The switch elements are activated when you depress the button and immediately reverse when you release. If you need to light up your switch panels, 55 Series pushbuttons offer a choice of incandescent or LED illumination. Choose incandescent if you want a bright display because of viewing distance or high ambient light levels. LED lamps last much longer and require less current. In either case, you get even, full illumination with every unit.
For positive on-off latching action, you want to choose a maintained pushbutton. Simply depress the button once and the switch contacts stay activated until you press it again. Perfect for on-off and function selection applications. As an added bonus, 55 Series maintained pushbuttons can be quickly changed to momentary by removing an internal spring and pin. You reduce stocking requirements. Just keep a supply of 55 Series maintained pushbuttons on hand and convert to momentary whenever needed.
When you need to know if a machine is on, when a circuit is activated, which alarm is warning about a danger, or that all systems are "go," a pilot light fills the bill. Simple but important, pilot lights serve as the vital interface between you and your equipment. Dependable 55 Series pilot lights are available in two styles to match your requirements. And, as with the illuminated pushbuttons, you can select between bright incandescent lighting or long-lasting, low-current, LED illumination. These pilot lights offer affordable quality for your indicator needs.
There are times when you need to select between two or three functions and only a rotary control will do. You may want to perform complex switching procedures or simply select an operating channel. 55 Series selectors offer you a wide choice of oil and watertight actions and features. Take your pick of knob or lever and bezel shape to fit your front panel design. Then decide on the combination of momentary and maintained actions that best suit your needs.
When security is a concern, there is no substitute for a keylock selector. You can lock a process on or off and then remove the key for tamperproof piece of mind. Other models require the key to be left in the switch at certain positions so it is always available for safety or convenience. The 55 Series keylock selectors offer all the specifications and benefits found with knob and lever selectors. They match front panel appearance and back of panel depth and will give years of dependable operation in harsh environments.
If a machine or instrument malfunctions or an emergency occurs, you want to shut down the equipment fast. A quick tap on the oversize actuator of a 55 Series emergency stop switch does the job. And for safety's sake, it requires a deliberate twist of the actuator knob or - for even more security - unlocking with a key to reactivate the switch. These attractive switches bring you the assurance of positive-acting, dependable EN 418 "foolproof" protection that is invaluable in times of emergency.
Alarm buzzers wired into your system provide front panel audible indication of equipment status or problems. Their piercing signal immediately attracts your attention. These units match other 55 Series components. Replacement buzzer elements also are available.
Alarm Buzzers provide a loud, audible signal that grabs your attention. Available in three different voltages, the 55 Series buzzers are styled to complement your existing panel devices. They match the depth behind panel of the Type B pilot lights for ease of wiring your alarm and status panels. Alarm meet the IP 40 standard.
