B-LINE E22LL2E – Frequently Asked Questions
1) Will the B-Line E22LL2E mushroom pushbutton fit a standard 22.5 mm panel cutout?
Yes. The E22 series is built around a 22.5 mm mounting hole, which is the standard cutout used across most industrial control panels and enclosure doors. If your existing panel is drilled for 22 mm devices, the E22LL2E mushroom head drops straight in.
2) Does the E22LL2E mushroom button latch when pressed, or does it spring back?
It latches. The E22LL2E is a twist-to-release operator, so once the mushroom head is pushed in it stays in until someone rotates it to reset. That is the behavior you want for an emergency stop or a maintained stop function, not for jogging or momentary control.
3) How many contacts does the B-Line E22LL2E come with, and what state are they in at rest?
Two normally closed contacts (2NC). At rest the circuit is made through both; pressing the mushroom head opens both. Two NC contacts let you break a control circuit and a separate monitoring or auxiliary circuit from the same operator. If your application needs an NO contact for a signal lamp or PLC input, this configuration will not provide one.
4) Is the E22LL2E a large mushroom head or the small 30 mm style?
It is the large mushroom operator in the E22 family. The oversized head is what makes it usable with a palm or a gloved hand rather than a fingertip, which is why this style gets specified for stop functions in plant and equipment panels.
5) Should I use a twist-to-release mushroom button or a momentary flush pushbutton for a machine stop?
For a stop that must stay latched until someone deliberately clears it, use the twist-to-release mushroom like the E22LL2E: pushed in, it holds the contacts open until the head is rotated. A momentary flush button releases the instant the operator lets go, so the circuit re-makes on its own. Use momentary for start, jog, and reset functions, and the maintained mushroom where the machine must not restart by itself.
6) What part number do I order for the B-Line large mushroom twist-to-release pushbutton?
Order B-Line E22LL2E. That is the complete 22.5 mm large mushroom operator with chrome bezel and two normally closed contacts, from the E22 series.
7) What is the bezel finish on the B-Line E22 mushroom pushbutton?
Chrome bezel. If you are standardizing a panel and the other E22 operators already installed carry the chrome ring, this one matches; a plastic-bezel device will read differently on the same door.
