LA38 Push Button Switch: How to Choose the Right Model for Industrial Control Panels
Choosing the right LA38 push button switch is important when assembling an industrial control panel or replacing an existing control button. Although many push buttons look similar, their contact configuration, operating mechanism and electrical ratings can differ.
Before ordering, buyers should check whether the switch matches the control circuit, mounting arrangement and intended operation.
Description
The LA38 series push button switch is used for manual control in electrical panels and industrial equipment. Depending on the model, push buttons may be available in different colors, contact arrangements and operating types.
Common options include momentary (spring-return) and maintained (self-locking) mechanisms. The correct selection depends on how the control circuit is designed to operate.

Applications
LA38 push buttons can be used in industrial control cabinets, machinery control panels, electrical distribution equipment and operator stations where manual switching is required.
Momentary or Maintained: Which One Do You Need?
This is one of the first questions to answer before purchasing.
A momentary push button returns to its normal position when released. It is commonly used where the control circuit requires a temporary input.
A maintained push button stays in its operated position until manually reset or released according to its mechanism.
These two types are not interchangeable in every control circuit.
What Should You Check Before Ordering?
For replacement projects, confirm the panel mounting hole size, button diameter, contact arrangement and operating mechanism.
Check whether the existing switch uses normally open (NO), normally closed (NC), or combined contacts. Also verify the electrical ratings and available installation depth.
Button color alone does not determine the switch function. The actual wiring and contact configuration must match the equipment's electrical design.
How to Avoid Ordering the Wrong Switch
A common mistake is selecting a replacement based only on appearance.
Two LA38-style buttons may look identical but use different contact blocks or operating mechanisms.
For a BOSTENE LA38 push button switch inquiry, provide the required color, operating type, contact configuration, quantity and existing model number if available.
A photo of the original switch and its contact block can also help clarify replacement requirements before ordering.
