Why Choose the EMAS H100DY Green Push Button?
The EMAS H100DY is a durable and reliable 30 mm green momentary push button switch designed for industrial control panels, electrical machinery and automation systems. As part of the EMAS H Series control unit range, it provides dependable manual switching for machine starting, control circuit activation and operator interface applications.
Featuring a spring-return mechanism and one normally open (1 NO) contact, the H100DY provides momentary switching operation. When the green actuator is pressed, the normally open contact closes to complete the control circuit. Releasing the button automatically returns the actuator to its original position and opens the contact, making it suitable for industrial start commands and other momentary control functions.
The EMAS H100DY features a flush-mounted green actuator, a practical modular construction and a 30 mm panel mounting format. Its IP50 protection rating provides protection against dust ingress in suitable indoor industrial environments. Designed for integration into electrical control cabinets and machine operator panels, this non-illuminated push button offers a straightforward and dependable solution for industrial switching applications.

Reliable Push Button Control for Industrial Machinery
Industrial push buttons such as the EMAS H100DY provide a simple and effective method of controlling electrical circuits and automation equipment. The normally open contact remains open when the button is not pressed. Pressing the actuator closes the contact, allowing a connected control circuit to respond to the operator's command.
The spring-return mechanism ensures that the push button automatically returns to its resting position after release. This makes the H100DY particularly suitable for start commands, PLC digital inputs, relay activation and motor starter control circuits where a temporary electrical signal is required.
The EMAS H Series combines practical industrial design with modular construction. The H100DY can be incorporated into machine operator panels and electrical control enclosures, while compatible EMAS B Series accessories provide flexibility for additional contact arrangements or suitable illumination configurations. Its green actuator makes it easy for operators to identify start and activation controls within a larger control panel.
Typical Applications
- Industrial machinery start and activation controls.
- Electrical control panels and operator stations.
- Motor starter and contactor control circuits.
- PLC input signalling and industrial automation systems.
- Conveyor and material handling equipment.
- Packaging and production machinery.
- Machine building and OEM control panel manufacturing.
- Relay activation and auxiliary control circuits.
- Manufacturing equipment requiring momentary manual switching.
- Industrial maintenance and replacement of compatible push button assemblies.
