• Tactile feedback
• Low behind-panel depth (21 mm max.)
• Stylish design
• Long life
This series has been developed on a modular base in order to fit the exact
needs of technicians and end-users.
❑ Installation options
The LPI series has a number of features to ensure easy installation:
• Front or rear mounting
• With or without sealing
• 2 separate circuits for NO/NC 5A version
• Terminal block connector for 0,1A NO version
• 3 different LED voltages: 6V, 12V, 24V
• Integrated LED resistor
❑ Aesthetic options
