A plurality of keys 13 are located above the circuit board 12 , and each key 13 includes a key cap 131 , a magnetic element 132 and a support device 133 . The keycap 131 is located above the circuit board 12 , and there is a stroke of the key 13 between the keycap 131 and the circuit board 12 (ie, a space for the keycap 131 to rise and fall). The keycap 131 has a top surface 131a and an opposite bottom surface 131b , and the magnetic element 132 is located in the keycap 131 . According to some embodiments, the magnetic element 132 is located on the bottom surface 131b of the keycap 131 (eg, the magnetic element 132 is adhered to the bottom surface 131b). According to some embodiments, a part or all of the magnetic element 132 is embedded in the bottom surface 131b (for example, by means of injection molding, the magnetic element 132 is embedded in the bottom surface of the keycap 131 , so that a part or surface of the magnetic element 132 is exposed. bottom surface 131b). The support device 133 is located between the keycap 131 and the circuit board 12 . In the raised state, the support device 133 provides a supporting force to support the keycap 131 to have a certain height in the vertical direction D1 . The supporting device 133 has elasticity. When the keycap 131 is pressed by a force (the force received is greater than the supporting force), the supporting device 133 provides a restoring force to restore the position of the keycap 131 .
