Implement state machine without using MCU

I want to implement a simple lighting circuit, which moves from one state to another using a simple momentary switch. The modes are as follows:
Bright mode -> Dim Mode -> Strobing mode -> Off

I want to use only one switch and minimum of components.

Hi,

I believe what you would need is a timing circuit, some logic gates, voltage regulator, switch, and leds for lighting. First, draw your state diagram. It should be simple and easy to understand. For your bright mode, a simple LED circuit would do. The circuit could contain your supply, leds, and lastly resistors. For your dim, what I would suggest is addition of resistance/ or in this case a varistor. Lastly, for strobing mode,look at the image attached, you can implement this. The parts used for the strobing are:
R1, R4, R5 = 680 Ohms,
R2, R3 = 10K
VR1, VR2 = 100K pot
T1, T2 = BC547,
T3, T4 = BC557
C1, C2 = 10uF/25V
Triac = BT136
